Make sure the new hard disk is detected do an

Code:

fdisk -l

: make sure you can see it in the list.

Once you identify the disk: e.g. /dev/sdc

We need to partition this disk ready for LVM.

Code:

fdisk /dev/sdc
n
p
1
press enter twice to keep default sizes (if not change it to the value you need)
t
8e = (makes the hard disk type lvm)
w
q

This should now should have created, the /dev/sdc1.

Now we have created the new disk, for lvm we need it as a physical volume:

Code:

pvcreate /dev/sdc1

Now since I don't have anymore information about what Volume groups and Logical Volumes you have I cannot give you the rest of the steps

paste the output of:

Code:

lvs

Then I can continue.

here is a real basic HOWTO guide for adding a new disk to an existing LVM.

Code:

vgextend  vg_computenode3 /dev/sdc1

Code:

lvextend  -L 10G  /dev/vg_computenode3/LogVol01 /dev/sdc1

Change the size to the amount of space you need to add.

Code:

resize2fs /dev/vg_computenode3/LogVol01

This resizes the Filesystem, where the Logical Volume is mounted.

You do not want to create a new filesystem over /dev/vg_computenode3/LogVol01 as it will erase your current data.

Remember you are extending the the VG.
